Firewall Settings

Overview

This section explains how to congure your Router’s rewall security features. The Router’s rewall security

settings allow you reduce the risk of unauthorized access to your network by prohibiting certain types of

inbound and outbound network trac and by allowing you to congure specic rewall rules.

To change your rewall security level, click the option next to the desired security setting. Next, click Apply to

allow the changes to take eect.

High security level only allows basic Internet functionality. Only Mail, News, Web, FTP, and

IPSEC are allowed. All other trac is prohibited.

Like High security, Medium security only allows basic Internet functionality by default.

However, Medium security allows customization through NAT conguration so that you can

enable the trac that you want to pass.

Low security setting will allow all trac except for known attacks. With Low security, your

Gateway is visible to other computers on the Internet.
